In its default configuration, the nginx server listens on port TCP/80 and TCP/443 and allows these
services to be used:

The agent management server (xivo-agentd)

The authentication server (wazo-auth)

The configuration server (xivo-confd)

The telephony service interface (xivo-ctid-ng)

The directory service (xivo-dird)

The AMI HTTP interface (xivo-amid)

web interface (xivo-web-interface)

API documentation (xivo-swagger-doc)

The websocket interface (xivo-websocketd)

Asterisk WebSocket (xivo-config)

An administrator can easily modify the configuration to allow or disallow some services.

To do so, an administrator only has to create a symbolic link inside the
/etc/nginx/locations/http-enabled directory to the corresponding file in the
/etc/nginx/locations/http-available directory, and then reload nginx with
systemctlreloadnginx. A similar operation must be done for HTTPS.
